Magus DF3 Darkfield Condenser NА 0.7-0.9 (85097)

This darkfield condenser is designed to enable darkfield microscopy, a technique used to observe unstained, translucent specimens that absorb very little light and are often invisible under conventional bright-field illumination.

For proper operation, the numerical aperture of the condenser must be higher than that of the objective. With a numerical aperture range of 0.7 to 0.9, the condenser is suitable for use with dry objectives providing magnifications from 4× to 40× and numerical apertures below 0.9.

The darkfield condenser is installed in place of the standard Abbe condenser in the microscope arm, allowing quick and efficient switching to darkfield observation.

To achieve a high-contrast image when using the darkfield technique, it is recommended to use a 0.17 mm thick cover glass together with a microscope slide measuring 1.0 to 1.2 mm in thickness.
